No, it is not possible to collect pure atomic ions as a mass of liquid or powder. Atomic ions are charged particles that are formed when an atom gains or loses electrons. They exist in a gaseous state or in solution when dissolved in a solvent, but they do not form a solid or liquid mass on their own.
In a gaseous state, atomic ions can be created and manipulated using techniques such as ionization and mass spectrometry. In solution, they can be found in the form of dissolved salts or electrolytes. However, isolating and collecting pure atomic ions as a solid or liquid mass is not possible because their stability and behavior are determined by the interaction with other atoms or molecules.
If you want to collect a solid or liquid mass of a specific compound containing ions, you would typically need to combine the appropriate positively and negatively charged ions to form a stable ionic compound, such as a salt. These compounds can then be collected as a solid or dissolved in a liquid.
